  • Publication number: 20060091511
    Abstract: A chip-on-board (COB) package has a flip chip assembly structure and is used for an integrated circuit (IC) card. The COB package has conductive patterns as contact terminals on an outer surface of a non-conductive film, and an IC chip on an inner surface of the film. The film has a number of holes through which the conductive patterns are partly exposed. A number of conductive bumps on an active surface of the IC chip face the inner surface of the film and enter corresponding holes in the non-conductive film to mechanically join and electrically couple to the conductive patterns. The disclosed COB package and a related manufacturing method allow a reduction in production cost, simplified process, better electrical connections, and improved reliability.

  • Publication number: 20060071303
    Abstract: Embodiments of the present invention are directed to a film substrate of a semiconductor package. The film substrate of the semiconductor package comprises a thin film insulating substrate and a thin copper circuit pattern. An inter-pattern groove between the thin copper circuit patterns is formed by laser etching. Accordingly, the embodiment improves electrical contact between the film substrate and a semiconductor chip mounted thereon, and improves the manufacturing process for the film substrate by adopting a simple laser machining to form the thin copper circuit pattern in lieu of a traditional wet-etching process that undergoes complex lithography steps.

  • Publication number: 20060003568
    Abstract: A method for manufacturing a tape wiring board in accordance with the present invention may employ an imprinting process in forming a wiring pattern, thereby reducing the number of processes for manufacturing a tape wiring board and allowing the manufacturing process to proceed in a single production line. Therefore, the manufacturing time and cost may be reduced. A profile of the wiring pattern may be determined by the shape of an impression pattern of a mold. This may establish the top width of inner and outer leads and incorporate fine pad pitch. Although ILB and OLB process may use an NCP, connection reliability may be established due to the soft and elastic wiring pattern.

  • Publication number: 20050285277
    Abstract: A circuit film having film bumps is provided for a film package. An IC chip is mechanically joined and electrically coupled to the circuit film through the film bumps instead of conventional chip bumps. In a fabrication method, a base film is partially etched by a laser to create an etched area that defines raised portion relatively raised from the etched area. Then a circuit pattern is selectively formed on the base film, partly running over the raised portions. The raised portion and the overlying circuit pattern constitute the film bumps having a height not greater than the height of the circuit film.

  • Publication number: 20050205524
    Abstract: A method of manufacturing a tape wiring substrate, by which the production cost can be reduced by a simplified manufacturing process. A fine wiring pattern having fine pitches can be formed. The method of manufacturing a tape wiring substrate includes preparing a base film, forming a metal layer on the base film, and processing the metal layer into a wiring pattern using a laser. In addition, the metal layer is partially removed using the laser, and a wiring pattern is formed by a subsequent wet etching.

  • Publication number: 20050121796
    Abstract: A tape circuit substrate includes a base film with first wiring and second wiring disposed on the base film. The first wiring extends into a chip mount portion through a first side and bends within the chip mount portion toward a second side. The second wiring extends into the chip mount portion through a third side and bends within the chip mount portion toward the second side. The first, second, and third sides are different sides of the chip mount portion. Thus, size and in turn cost of the base film are minimized by arranging wirings within the chip mount portion for further miniaturization of electronic devices, such as a display panel assembly, using the tape circuit substrate.

  • Patent number: 6903451
    Abstract: In accordance with the present invention, a chip scale package (CSP) is manufactured at wafer-level. The CSP includes a chip, a conductor layer for redistribution of the chip pads of the chip, one or two insulation layers and multiple bumps, which are interconnected to respective chip pads by the conductor layer and are the terminals of the CSP. In addition, in order to improve the reliability of the CSP, a reinforcing layer, an edge protection layer and a chip protection layer are provided. The reinforcing layer absorbs stress applied to the bumps when the CSP is mounted on a circuit board and used for an extended period, and extends the life of the bumps, and thus, the life of the CSP. The edge protection layer and the chip protection layer prevent external force from damaging the CSP. After forming all elements constituting the CSP on the semiconductor wafer, the semiconductor wafer is sawed to produce individual CSPs.
